Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, [1] resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging.
Feline odontoclastic resorption lesion (FORL) is a syndrome in cats characterized by resorption of the tooth by odontoclasts, cells similar to osteoclasts. FORL has also been called Feline tooth resorption (TR), neck lesion, cervical neck lesion, cervical line erosion, feline subgingival resorptive lesion, feline caries, or feline cavity.
Bruxism is excessive teeth grinding or jaw clenching. It is an oral parafunctional activity ; [ 1 ] i.e., it is unrelated to normal function such as eating or talking. Bruxism is a common behavior; the global prevalence of bruxism (both sleep and awake) is 22.22%. [ 2 ]
This article was the first to establish abfraction as a new form of lesion, differing from abrasion, attrition, and erosion. [ 2 ] Tooth tissue is gradually weakened causing tissue loss through fracture and chipping or successively worn away leaving a non-carious lesion on the tooth surface.
Although it cannot cause periodontium damage in itself, [19] bruxism is known to be able to worsen attachment loss and tooth mobility if periodontal disease is already present. [20] Moreover, the severity of tooth mobility caused by bruxism also varies depending on the teeth grinding pattern and intensity of bruxism. [ 21 ]
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
Bruxism is an oral parafunctional activity where there is excessive clenching and grinding of the teeth. It can occur during sleep or whilst awake. It can occur during sleep or whilst awake. The cause of bruxism itself is not completely understood, but psychosocial factors appear to be implicated in awake bruxism and dopaminergic dysfunction ...
Attrition (research), loss of participants during an experiment. Attrition (dental), loss of tooth structure by mechanical forces from opposing teeth; Attrition (erosion), the wearing away of rocks in rivers or the sea; Attrition, also known as Final Mission, 2018 american film; Imperfect contrition, also known as attrition, in Catholic theology
